When I resume the PC from the suspend mode to the normal mode as the memory stick is kept inserted, the window of the S drive appears on the display.

With VAIO Action Setup, I set my PC to launch Explorer automatically when I insert or remove a memory stick. When I resume the PC from the suspend mode to the normal mode as the memory stick is kept inserted, the window of the S drive appears on the display. Once I made a setting with VAIO Action Setup, this symptom appears on rare occasions even if I cancel the setting.

They are the specifications of the memory stick driver.

Put your PC in the suspend mode in the state that Explorer is running and the window of the S drive does not automatically appear at the time of the resumption of the PC from the suspend mode, even if the memory stick is kept inserted in your PC.
